Technical field
The present invention relates to image processing system, relate to more in detail the image processing system of the electrofax modes such as printer, duplicating machine, facsimile unit.
Background technology
In the image processing system of this electrofax mode, knownly when imaging, can discharge the number of chemical material.Representational can enumerating in the chemical substance that discharges (chemoluminescence thing): toner dust that produces when the ozone that when photoreceptor is charged, produces, development or photographic fixing etc.At present, taked following countermeasure: its generation self decline is implemented to process and made to the generating source of these chemoluminescence things, or for the material that produces is not discharged filtrator etc. is set outside machine.For example in (Japan) the Unexamined Patent 5-150605 communique, be provided with for the division board of the ozone that will produce to the ozonolysis equipment guiding at machine intimate.
Patent documentation 1: Unexamined Patent 5-150605 communique
But nearest raising along with worldwide environmental protection consciousness; be taken seriously from the situation of the image processing system generation of the electrofax mode ultramicron different with the toner dust from ozone (Ultra Fine Particles has the following particle diameter of 100nm).Up to now, owing to the machine intimate at image processing system is where to produce this ultramicron and unclear, so there is not effective countermeasure.Therefore, think that above-mentioned ultramicron is polluting machine intimate and surrounding environment.
The result of present inventor's research is, in the image processing system of electrofax mode, this ultramicron mainly produces at fixing device, and the rubber layer that comprises from the fixing member (roller and band) of the pressure contact portion that is formed for photographic fixing more in detail produces.
Summary of the invention
So problem of the present invention is to provide a kind of image processing system, can prevent that by catching the ultramicron that produces from the rubber layer of fixing member machine intimate and surrounding environment are contaminated.
At this, shown in Figure 15 (A), general fixing member 300 comprises matrix 301 that the seamless-band by mandrel cylindraceous or ring-type consists of, cover the outer peripheral face of this matrix 301 and the rubber layer 302 that arranges, cover the outer peripheral face of this rubber layer 302 and the top layer that arranges 303 these three layers.In this example, be provided with the well heater 305 for the target temperature that fixing member 300 is heated to regulation (180 ℃ ~ 200 ℃ scope in fixing temperature) in the inner space of matrix 301.Rubber layer 302 is made of silastic material, has for the thermotolerance of above-mentioned fixing temperature and is used for guaranteeing the elasticity of pressure contact portion length.Top layer 303 is for example by PFA(tetrafluoroethene perfluoroalkyl vinyl ether multipolymer) consist of, help tablet recording materials such as () paper usings by pressure contact portion to peel off.Along on the direction of matrix 301 central shaft C, the end 302e of above-mentioned rubber layer 302 and the end e on above-mentioned top layer 303 lay respectively at the inboard of the end 301e of above-mentioned matrix 301.

In the present embodiment, near relative body housing 101 fixing roller 300 and have via not shown frame and be supported fixing passage 30.Passage 30 also can consist of by have in stable on heating resin material or the metal materials such as aluminium and iron any for above-mentioned fixing temperature.
As understanding from Fig. 4 (A) like that, this passage 30 comprises: around mandrel 301 along circumferentially at a pair of introducing port 31 towards the position setting of the end 302e of rubber layer 302,31(has only represented the introducing port 31 in Fig. 4 (A) left side), respectively with these introducing ports 31,31 top is communicated with and from introducing port 31,31 top is a pair of first vertical component effect 32 of (Z direction) extension upward vertically, 32, respectively with these the first vertical component effects 32,32 top is communicated with and from the first vertical component effect 32, the a pair of horizontal part 33 that 32 top is converged at the position corresponding with the central portion of fixing roller 300 to horizontal direction (directions X) extension, 33, with these horizontal parts 33,33 converge that the position is communicated with and converge upward vertically (Z direction) second vertical component effect 34 of extending of position from this.The top of this second vertical component effect 34 is outlets 35 of passage 30.
As understanding from Fig. 4 (B) like that, the introducing port 31 of passage 30 is with the roughly complete cycle encirclement except the part of joining with backer roll 131 of the periphery of fixing roller 300.The outer peripheral face of circumferential end face (upper and lower end face) 31a of introducing port 31, the relative fixing roller 300 of 31b has with gap a little and is closed.
As shown in Figure 5, from the section along fixing roller 300 central shaft C, the introducing port 31 of passage 30 has: than the end 302e of rubber layer 302 also near the first side wall 31e of mandrel 301 end 301e, than the end 302e of rubber layer 302 and the second sidewall 31i far away apart from mandrel 301 end 301e.
Be adjacent at the relative part 301a1 of the first side wall relative with the first side wall 31e of passage 30 among the outer peripheral face 301a of mandrel 301 and be coated with the sleeve 39 with thermal insulation.The inner periphery 31e1 of the first side wall 31e of passage 30 leaves from the outer peripheral face a of sleeve 39.
Be equipped with at the inner periphery 31i1 of the second sidewall 31i and have thermal insulation and flexible seal member 38.The inner periphery 31i1 of the second sidewall 31i via seal member 38 with the outer peripheral face 303a on top layer 303 in the relative part 303a1 of the second sidewall join.Because top layer 303 has release, thus during action around the central shaft C of fixing roller 300 rotation the time, the relative seal member 38 of the relative part 303a1 of the second sidewall on top layer 303 successfully slides.And utilize the buffering of seal member 38, can prevent that the inner periphery 31i1 of the second sidewall 31i from directly contacting and injury with the outer peripheral face 303a on top layer 303.
Shown in Fig. 4 (A), Fig. 4 (B), be provided with the end 302e of the rubber layer 302(that can catch fixing roller 300 at the position of second vertical component effect 34 inner export-oriented 35 of passage 30) filter element 37 of the ultramicron G that produces.The trade name of filter element 37 is identical with the filter element 14 of the first embodiment with function.
Be the equal of that the position of filter element 37 upstream sides is provided with the vent fan 36 as the air-flow generating unit in the second vertical component effect 34 inside of passage 30.Utilize this vent fan 36 and can produce reliably from introducing port 31 to passage the air-flow of 30 outlet 35.
Image processing system with this structure utilizes well heater 133 that fixing roller 300 is heated to the interior fixing temperature of 180 ℃ ~ 200 ℃ scopes.Make the paper using 90 of transporting with the outer peripheral face 303a crimping of fixing roller 300 to paper using 90 photographic fixing images.
When fixing roller 300 is heated to above-mentioned fixing temperature, then produces the ultramicron G(such as siloxane from the rubber layer 302 of fixing roller 300 and have particle diameter below the 100nm).Because the outer peripheral face 302a of rubber layer 302 is covered by top layer 303, so ultramicron G will be from the end 302e ejection of rubber layer 302.
At this, in this image processing system, be from the ultramicron G of the end 302e of rubber layer 302 ejection from around mandrel 301, being imported in the passage 30 along the introducing port 31 that circumferentially arranges in the position towards the end 302e of rubber layer 302.The ultramicron G that is directed in the passage 30 flows to the outlet 35 of passage from first vertical component effect 32, horizontal part 33 and second vertical component effect 34 of introducing port 31 by passage 30 along with the air-flow of vent fan 36 generations.The filter element 37 that is arranged on export-oriented 35 positions of passage 30 by passage 30 mobile ultramicron G is caught.Consequently can prevent that according to this image processing system machine intimate and surrounding environment are contaminated.
As shown in Figure 5, in this image processing system, the inner periphery 31e1 that consists of the first side wall of passage 30 introducing ports 31 leaves (therefore leaving from the outer peripheral face 301a of mandrel 301) from the outer peripheral face 39a of sleeve 39.Therefore, the gap 31e1 between the outer peripheral face 39a that near the air the introducing port of passage can be by sleeve 39 and the inner periphery 31e1 of the first side wall 31e and to passage 30 interior inflows.Vent fan 36 is easily produced from the air-flow A of introducing port 31 towards the outlet 35 of passage 30.
